Answer:
difference means subtraction operation.
let the number be n :
[tex](5 \times n) - 7 = 53[/tex]
arrange the equation:
[tex]5n - 7 = 53[/tex]
______________________________________
---------------------------♦ end ♦----------------------------------
further more [ getting value of n ]
add 7 on all sides:
[tex](5n - 7) + 7 = 53 + 7 \\ 5n = 60[/tex]
divide all sides by 5:
[tex] \frac{5n}{5} = \frac{60}{5} \\ \\ n = 12[/tex]
